Abstract
In this paper, we present a new modulation scheme for transmission over OFDM, named Pilot-Single Sideband modulation (P-SSB), enabling data transmission even in channels with very low correlation levels in both frequency and time domains. P-SSB modulation achieves this feat through the combined use of the particular properties of the Hilbert Transform and the powerful decoding abilities of turbo-equalizers. We show that in the case of QPSK constellation with transmission over OFDM, the proposed modulation scheme enables reliable data transmission in channel conditions where other transceiver designs fail. Finally, we establish by mean of numerical performances evaluation the existence of the operation region in which the proposed scheme is preferable to conventional pilot-based transmission schemes and present useful metrics to determine its boundaries
